1) do you apply more force to get the block started in motion or to maintain it

Question

1) do you apply more force to get the block started in motion or to maintain it in motion?
2) is the static friction or the kinetic friction force larger?
3) when is the normal force on an object equal in magnitude to the weight of the object? When is it different in magnitude?

Explanation / Answer

here,

1)

we have to apply more force to get a block started in motion

force is required to accelrate a motion

2)

the static friction force is larger than the kkinetic friction force

3)

the normal force on an object is equal to its weight when the object is on a horizontal plane and their is no other vertical force acting on it

it is different in magnitude when the object is on incline plane or their is any other vertical force acting on the object
